When I was starting out my first junior position I was really good at Regex. I ended up becoming the go-to guy for complex database migrations since I could convert a huge C# "script" into a really simple SQL script that used Regex to find certain patterns and convert them into the required formats, etc.

These SQL scripts would do the job in a fraction of time (like days down to hours or hours down to minutes).

Eventually, I became the go-to for front-end stuff.

Then other stuff after that.

One of the main things I've gleaned from my career is that you need to be the "go-to" for something in order to stick out.

Sometimes is just a matter of discovering a gap in knowledge on your team - and filling it!
